Let's say 2C = lnA





Now you should have been given values of y and t to enable you to work out A.

For what follows I'm going to assume lnA = 1











So it does seem to give that function.

Okay, but the result of this equation is  that y(t) is a complex function ( y = sqrt(-(t+1))/t ). Can this be the right answer?

How exactly do you separate?

hi yago.dorea

Welcome to the forum.

Separation, the partial fractions for y and 'function of a function' for t.

I'm getting

I want to solve the following ODE:

(1 + t)y' = ty(1 + y)   where y = y(t).

If I try to solve it by separation, I get complex roots, but I'm not trained yet to deal with them. sad

What should I do?
